Carbon remover



Patented July 26, 1932 UNITED STATES JOHN HOWARD ISSICK, OF ERIE, PENNSYLVANIA I cannon remover;

to Drawing. Appfldption med April 4,

This invention relates compounds for use in the cylinders of an iiiternal combustion engine 7 for effecting the removing of carbon therefrom. I

The primary object of the present invention is to provide a carbon remover for internal combustion engines which, when insorted into the engine cylinders, will penetrate to all parts thereof and thoroughly 0 soften the carbon to such a degree that upon the subsequent running of the engine it will be easily dislodged from the cylinder wall and from the piston and expelled throughthe engine exhaust passages.

Another objectof the invention is to provide a carbon remover which, in addition to thoroughly softening the carbon, will leave upon the cylinder wall and upon'the valve stems of the engine an oil deposit which will so lubricate the same.

The composition consists of a mixture of volatile and non-volatile fluids. The composition. is inserted into the engine cylinders while the same are in a heated condition so that the volatile fluids thereof will be rapidly vaporized and this vapor or gas will penetrate every part of the chamber and will thoroughly soften the carbon therein. The non-volatile constituents are deposited on the surfaces of the cylinderw'all and valve stems and act to lubricate the same.

The composition embodying the present invention consists of the following ingredients combined. in the appended approximate proportions for the making of a gallon batch of the product.

Gallons Benzol (90 proof); 18 A;

Acetone (dimethyl ketone) 16 Alcohol (denatured-188 proof) 12 Oil of cedar wood (grade-J]. 8. P3" 1 Camphorated oil (grade-U. P. 1 Turpentine; i 1

The ingredients enumerated are mixed together in the order given and the composition is ready for use. V

The carbon remover is used by inserting the necessary quantity of the same-in each of the cylinders of the motor vehicle engine, through the spark plug holes thereot, the inposition,

sertionof the composition being made while the cylinders are hot. The composition immediately forms a gas through the evaporation of the benzol, acetone, alcohol. and the camphor of the camphorated oil which penetrates to all parts of the cylinder and works into the carbon to change it to a pasty condition. The motor is then allowed to stand for approximately twenty minutes with this composition in the cylinders, after which it is 00 started and raced a second ata time for approximately a minute. This operation of the engine causes the carbon to break away from the cylinder walls and from the piston and pass out of the engine through the exhaust 55 ports.

The non-volatile constituents of the comsuch as the; cotton seed oil of which the camphorated oil is made, the oil of cedar wood and the turpentine, are deposited on the moving parts of the machine and operate to lubricate the same.

Should the carbon in the engine be badly crystallized several treatments with the composition, in the manner above outlined, may be necessary to soften the carbon to the point where it will leave the cylinder and will not get between the wall of the same and the piston and cause scoring of the cylinder wall.

-While denatured alcohol has been called for in the formula, it will, of course, be understood that grain or ethyl alcoholmay be employed in the pure state or methyl alcohol may also be used if desired.

It has been found, as a resultfilof experimentation, that various quantiti "s of the present composition may be employed in the engine cylinders with good results,$but it has been found that thebest results are obtained through the use of approximately onefiuid ounce of the preparation in each cylinder.

Having thus described the invention, what is claimed is:

1. A carbon remover of the character described, consisting of benzol, acetone, alcohol, oil of cedar wood, camphorated oil and tur" pentine. 1

2. A carbon remover'for internal combustion engines, consisting of the following ingredients taken in the appended up ro ximate proportions for the production a 50- gallon batch:

e p a 11 .Benzol (90 proof) 58 Acetone (dimethyl ketone) 16 Alcohol denatured 188 proof 12 Oil ofce ar-wood (grade-'U. .P.) 1 Camphorated oil (grade-U. S. P.) 1 p Turpentine 1 In testimony whereof I hereunto aflix my signature.
